Noted young adult author Ridley Pearson will be making a signing appearance at the Walt Disney World Resort on April 4 and April 5, 2011 to promote his latest entry into the popular Kingdom Keepers series, Kingdom Keepers IV: Power Play. Available nationwide on April 5, 2011, Walt Disney World guests will have the exclusive opportunity to purchase it the day before at Once Upon A Toy, located in the Downtown Disney Marketplace.

Disney (e)readers, rejoice! At last, classic beloved series and books from the prolific authoring team of Ridley Pearson and Dave Barry will be released in the Amazon.com Kindle eBook format later this month. First, the exciting prequel series to Disney’s Peter Pan, Peter and the Starcatchers by Ridley Pearson and Dave Barry will be released on November 23. The remaining books and series will be released in Kindle format on November 29.

The next in the incredibly popular series which centers on what happens inside the Walt Disney World theme parks at night (at least until they hit the high seas of the Disney Cruise Line in book five), Power Play ‘s official synopsis is as follows:

In honor of the release of his third entry in the Kingdom Keepers series, Disney in Shadow, New York Times best-selling author Ridley Pearson recently escorted a group of young fans from Windy Hill Middle School in Clermont, Florida on a special Kingdom Keepers tour through Epcot at the Walt Disney World resort.

Five teenagers – the Kingdom Keepers – have been transformed into Disney Holographic Images (DHIs) that thrill guests as they guide them through each of the Disney parks. In truth, the Disney Imagineers created the DHIs to protect Disney’s theme parks from the Overtakers, classic Disney villains, who are trying to seize the parks and use them for their own evil agendas. Ridley Pearson’s Kingdom Keepers book series follows these heroes on behind-the-scenes adventures in the magical world of the Disney parks – and in Kingdom Keepers III: Disney in Shadow, the action happens in Disney’s Hollywood Studios and Epcot. (Disney-Hyperion Books, ages 10 and up, $17.99)

Via his blog, author Ridley Pearson has made the second chapter of Kingdom Keepers III: Disney in Shadow available for download. Previously, Pearson has made the first chapter available as we reported earlier.

The full book from Disney Hyperion will be available in stores on April 6.

On his official blog, Ridley Pearson, popular author of young adult novels, has made the first several pages of his upcoming title Kingdom Keepers 3: Disney in Shadow (April 6, 2010; Disney Hyperion) available for download (Adobe Acrobat Reader required). The newest book in the series has our heroes back in the theme parks of Walt Disney World with a new challenge, obstacles and enemies to overcome.

As Ridley has promised us, Stitch has a prominent role in the book, appearing first on page one, but his badness level appears to be questionable at best. Only time (and the rest of the book) will tell if Stitch counts Maleficent and the Overtakes or Finn and the rest of the DHIs amongst his ‘ohana.

Through his twitter, Kingdom Keepers author Ridley Pearson has announced that the developers of the Kingdom Keepers online game are now accepting applications for beta testing. The only requirement for applicants is that they are at least 13 years of age.
